when i was younger i had recurring nightmares about a specific TV channel's ad jingle, like a physical materialization of the word "ad" (in french) would appear in my house when the jingle played on TV and would try to kill me for whatever reason

the funniest thing about this is that at some point while growing up i actually befriended the thing in my dreams? and in later nightmares i had i would sometimes call it to help me, stuff was wild honestly
